Fanfic / Friendly Foreign Exchange Student Spider-Man!

Image by Ozlyk.

Friendly Foreign Exchange Student Spider-Man! is a crossover story written by Zaru and co-written by LD1449 and IKnowNothing. Taking place just after Peter Parker, Spider-Man, turned to dust at the end of Avengers: Infinity War. Here, instead of simply ceasing to exist, he awakens on a rooftop in the world of My Hero Academia (MHA for short) at the very beginning of that story. Peter proceeds to work towards becoming a hero in a world similar to but very different from his own, where many of the things that once held him back simply do not exist anymore. His current goal is to graduate from U.A. and honor his promise to Tony Stark to become the greatest hero he can be, even if it isn't in his home world.

The thread with the story can be found on spacebattles.com here, FanFiction.Net here and on Wattpad here.

Friendly Foreign Exchange Student Spider-Man! provides examples of:

• Absurd Phobia:
  • Even after surviving the USJ Incident and the Sports Festival, Izuku is still unnerved by elevators, clowns, and his neighbor's large dog.
  • Peter's reaction to finger snaps would count as this in-universe, even if every reader knows exactly why such a fear is very very well-founded.
• Abusive Parents: Endeavor, like the anime and manga, only sees Shoto as a means to surpass All Might, and berates him when he fails to meet expectations.
• The Ace: Peter has scored so well on all the tests at UA so far that he earned this nickname by the second day of classes. It isn't wholly undeserved with how high he scored on the entrance exams practical and the fact that he scored the highest on the physical evaluation on the first day. He really cements his status as the ace of the first years during the Sports Festival. First, he blows past everyone in the obstacle course, finishing before anyone else even makes it to the Fall, and sets the second-highest record for finish time in the school's history. Then during the War of the Flags, he fends off everyone who tries to stop him, at one point taking down Eijiro, Tetsutetsu, and Mina at the same time. It gets to the point that he starts to garner a reputation as "the next All Might".
• Adaptational Badass:
  • Thanks to the confidence boost she got from hanging out with Peter, Pony is much more formidable than her canon counterpart. Not only does she manage to take second place in the obstacle course at the Sports Festival, but she makes it to the tournament portion, where she nearly beats Bakugo in the second round.
  • Momo actually gets a chance to actually fight in Battle Training. That leads to her having enough experience and confidence to kill the Nomu, something that even manages to surprise All for One. The death of the Nomu leads to a harsher case of Heroic BSoD which Momo then overcomes earlier than canon. She also performs much better in the Sports Festival.
  • Stain manages to escape the Hosu fight, despite fighting Pro Hero Yoroi Musha and Momo. Played with because neither hero receives any significant injury, while Stain receives serious damage and is forced to escape.
• Adaptational Early Appearance: Both Dabi and Toga appear before the Sports Festival arc.
• Adaptational Wimp: Downplayed. The Hero Killer Stain isn't nearly as big of a threat here as he was in canon. While it took the combined might of Izuku, Shoto, and Iida to exhaust canon!Stain into submission, here Izuku and Peter were able to dispatch fanfic!Stain fairly quickly. This is done with realistic consequences at play, as while he actually succeeded in killing Native, by the time Izuku and Peter find him he was already worn down from a fight against Yoroi Musha and Momo, not to mention that Peter has way more experience and a larger threshold of abilities than his peers and Izuku was able to figure out how to manage One For All earlier and thus has more experience in using it.
• Adapted Out: In case you're wondering whose place Peter takes in Class 1-A, it's Mineta. Though he does make a few brief cameos: during the entrance exam griping about how Peter's grabbing all the points, and during the Obstacle Race as a Gen-Ed student.
• Aggressive Categorism: Bakugo's go-to insult towards Peter is the fact that he is American, and thus doesn't deserve to be in UA. While at first it was a case of Underestimating Badassery, by now it's just a way for him to hide his envy towards Peter's superiority.
• All Webbed Up: Peter uses his web-shooters as his main means of restraining people, and even gets them authorized for use at the Sports Festival. Likewise, Momo finds his web fluid formula so effective, that a paintball gun loaded with web balls becomes one of her go-to weapons.
• Alternate Universe: Word of God has stated that this universe is separate from Avengers: Endgame, and that Peter Parker won't be returning to his native universe. It's also possible that this version of Spider-Man is the result of at least one of the 14 million failed timelines where the Avengers lose against Thanos.
• Always Second Best:
  • It only comes up in a passing conversation, but Mt. Lady expresses envy towards Ant Man over the fact that he can control his size easier than she can and has more options regarding how he does so (can shrink as well as grow).
  • Despite Midoriya getting along well with Peter, he tends to negatively compare himself to his friend. Due to Peter's greater mastery of his powers and accomplishments, Midoriya feels like a second-fiddle thanks to his lack of control over his abilities and low self-esteem. This goes up even further when people start comparing Peter to All Might, worsening Midoriya's sense of self-worth as a hero-in-training and All Might's successor.
  • Bakugo lost his first place entrance exams slot to Peter and was bumped further down on the physical fitness test on the first day of school and it infuriates him. During the Sports Festival, he's absolutely pissed when Peter beats him on the obstacle course and fends him off in War of the Flags. Once people start comparing Peter to a young All Might thanks to his performance, Bakugo's rage reaches new heights. After Bakugo ends up on the wrong side of a brutal Curb-Stomp Battle against him, he's forced to face the reality that Peter is better than him in all categories and he has barely made a scratch on him.
  • Something that Endeavor berates his son for is how, despite being in the top 5 in his class, he's overshadowed by Peter. This also bothers Shoto, since if there is someone who surpasses him while he tries to only use his Ice-half, he runs the risk of breaking his vow to never use his Fire-half.
• ...And That Would Be Wrong: When Yu makes a note how she will tolerate Karen's presence as long as she does not attempt to take over the world, Karen responds that it would be too easy given how weak network security is in this world, only to say that it was a joke and that the Ultron Safeguard would not let her if she wanted to.
• Angelic Beauty: Peter notes that Ibara Shiozaki is this.
• Animal Motifs: Peter, Tsuyu, Tokoyami, Setsuna, and Pony all enact this with spiders, frogs, birds, lizards, and horses respectively.
• Anime Hair: Many people Peter sees have this, seeing as he's in an anime series now. He justifies it by assuming it as an effect of their Quirks.
• Arachnid Appearance and Attire: Peter's hero name is Spider-Man, he can cling to walls, his (Iron Spider) costume sprouts spider-like robot legs, and he uses web-shooters to swing about and trap people. He fits this to a T.
• Armor-Piercing Question:
  • After Mirko accuses Peter of being a Death Seeker, Peter begins to openly question if he was as sane as he thought he was considering everything he's been through.
  • When Bakugo raves that Izuku lied about being Quirkless and looked down on him their whole lives, his father questions if he's absolutely 100% sure about this and tells him not to lie about it. Bakugo is completely unable to provide an answer and only responds in Stunned Silence.
  • Just like on canon, Midoriya's match with Todoroki can be summed up as "Do you want to be a hero?"
• Ascended Extra: Mt. Lady is given more focus and depth here due to Peter being her ward; same with Pony, who becomes Peter's first friend in Japan plus taking Mineta's place in 1-A. Also, due to several students choosing different mentors for their internships, some Pro Heroes appear sooner than in canon with expanded roles as well.
• Asian Speekee Engrish: Many of the students at UA do this once they realize that Peter is American. Some are better than others, but Peter notes that they all have fairly thick accents.
  • Peter gets the inverse of this while learning to speak Japanese.
• Be Careful What You Wish For:
  • Aizawa continuously tries to make Peter stop quipping all of the time because he doesn't like it, thinking that it's Peter not taking things seriously. And then he sees what is the one true thing that would make Peter stop being a wisecrack: being so pissed off that he is willing and able to try to kill whatever or whoever drove him to such a level of wrath.
  • During his internship, Mirko encouraged Peter to take the initiative and become a Pragmatic Hero. She regrets it when Peter's initiative gets him to go against her wishes, and goes after Stain on both personal (hurting a classmate) and pragmatic (having a good idea of his whereabouts and needing to act before he escapes) reasons, as Mirko risks her personal reputation if her intern gets injured while going solo.
• Beleaguered Assistant: Kurogiri doesn't really like Tomura and considers his master's protégé to be a bratty manchild with daddy issues. Regardless, he dutifully acts as his caretaker out of loyalty to All for One.
• Berserk Button: Bakugo unknowingly pushes Peter's when he indirectly insults the Avengers in chapter 23.
• The Berserker: Bakugo is considered a "genius berserker" by Aizawa, and it shows. The guy can't even clean his house without being violent about it.
• Beware the Nice Ones: Referenced by All Might, who knows just how dangerous those who always try to stay positive can become once pushed too far. It's the only reason he is able to see the signs and step in, in time to prevent Peter from accidentally killing Bakugo during the final match.
• Big Damn Heroes: During the USJ incident, Shigaraki holds Peter hostage, focusing on those who have thwarted his efforts directly (Peter, Momo, and Bakugo especially). Because he's so focused, he completely forgets that there's another hero trainee there. Thankfully, Izuku is able to remind him with a nice, friendly Smash.
  • Yoroi Musha swoops in to save Iida from Stain.
• Big Sister Instinct: Mt. Lady has become very protective and concerned with Peter's well-being. The minute she hears about what happened at the USJ, she rushes right to Peter's side.
• Big Sister Mentor: Mt. Lady for Peter, becoming his guardian and encouraging him to pursue the path of heroism.
• Bishoujo Series: Lampshaded by Peter, who notices that just about every girl he meets in Japan is very attractive. He even notes that many of the girls at UA fit into their own archetypes. Momo is the class' top model, Ochako is the Girl Next Door, Mina is the exotic-looking girl, Ibara is the choir girl, and Itsuka is the Cool Big Sis.
• Blow You Away: All Might and Thirteen use their quirks to simulate hurricane-level winds for the Natural Disaster exam.
• Bomb Disposal: One of 1-B's final exam's emergency simulations. Unable to disarm or disassemble the bomb, Pony passes the test by using her horns to levitate and carry the bomb to detonate it at a safe distance.
• Break the Haughty: Occurs at least twice during the Provisional License Exam:
  • Monoma is left stammering when he learns that he was The Load of his team.
  • Bakugou undergoes a minor Heroic BSoD when he learns he got the lowest passing score.
• Broken Ace: Peter still hasn't recovered from the events of Infinity War, and he's been losing sleep. He also gets PTSD flashbacks to those traumatizing events, triggered by seemingly innocuous things, such as fingers snapping or mention of things getting turned to dust (like Space Hero Thirteen or Shigaraki's powers do). In addition, he's still coming to terms with the fact that this is not his world and that the chance of seeing his loved ones again are pretty low.
• Cassandra Truth:
  • Like canon, Midoriya tries to tell Bakugo that he just got his Quirk and that it's a borrowed power. He doesn't believe him and thinks he's lying.
  • This happens when All Might tries to console Bakugo after his brutal loss to Peter in the last round of the Sports Festival. He tries to tell him that he has lost before (using the loss of his mentor to explain it to him). However, Bakugo's entire worldview of All Might is that he's an Invincible Hero who can never lose no matter the challenge, so he cannot accept that All Might can ever lose at anything. This results in him lashing out at him, accusing him of lying just like Midoriya was, despite telling the truth to him.
• Character Development: For Bakugo, it's subtle but there as he starts showing more respect for others, just in his own way.
• Chekhov's Gun: Shigaraki's "Father's" hand, the one he keeps over his face. Because it was destroyed and left behind during the USJ Incident, police are able to identify it as belonging to Shimura Kotarou, indicating a connection to both Shigaraki and All For One.
• Chick Magnet: Oh, Peter... He's strongly teased with Yaoyorozu, is genial and friendly to Pony, and Mei Hatsume outright drools over his intelligence.
  • Of the three, Pony is a good friend of Peter's and is the only one who seems to be actively pursuing him romantically. This is tempered, however, by him not noticing this.
  • Mei, while attractive enough and having science in common with Peter, isn't seen chasing him at all and seems to purely be interested in his tech.
  • Momo is a good friend of Peter's and the first person he's trusted his Web Fluid formula to, as well as the only one of the three that he's actively attracted to.
• Clarke's Third Law: When discussing Peter's reality, Araki mentions that most heroes in the MCU don't have anything that they would call a Quirk, but the technology that some of them use, such as Iron Man's suits and Pym Particles, is so advanced that the distinction between a normal person and one with powers becomes irrelevant.
• Combat Pragmatism: Mirko's fight style, in contrast with Peter's Fighting Clown one. As she points out, her quirk isn't too flashy or spectacular yet is still very powerful, so it's better suited to end battles as quickly as possible.
• Complaining About Rescues They Don't Like: Mineta cameos in the entrance exam fleeing from a three-pointer and when Peter rescues him, he tries to claim that he was going to trap the robot and accuses Peter of stealing his points. Peter notes that he can’t see any trap as he leaves.
• Crazy-Prepared: Peter was this for the entrance exam. He was one of the only ones to bring in not only support items to help him but also a full-on hero costume.
• Culture Clash: When Peter first starts out, he gets in trouble for stepping into a hero vs. villain fight, as this world has strong laws against unregistered heroism. This is a realistic result of two hundred or so years of Quirks and powers being publicly accepted things and an attempt to prevent unqualified people from getting in the way of professionals. Whereas in Peter's home universe, people with powers and abilities have only really come into prominence in the past ten years with the debut of Iron Man. (While there were heroes such as Captain America, Captain Marvel, and Ant Man, who did appear before Iron Man, they were either kept hidden from the public, deliberately kept themselves out of the public eye, or were one-offs.) As such, the MCU world doesn't have laws to deal with powered vigilantes yet.
  • What makes this trope worse for Peter is that he can't speak a single word of Japanese – it takes him a year to be able to speak it fluently and prepare for the UA exams, and even then he still stumbles over cultural norms of the Japanese people.
  • When Spider-Man made his debut in the MCU, Iron Man was immediately chewed out for bringing a kid on the cape scene, and Tony himself felt a bit ambivalent over it. By contrast, the Quirkverse openly encourages Peter's heroic aspirations and gives him a perfectly legal way to make a career out of it.
  • In Japan, bullying isn't viewed as too bad of a problem and is seen as just another thing to deal with while growing up. Peter comes from America, however, where there is a much stronger aversion to bullying, and as such doesn't see Bakugo as "a strong-willed guy with an interesting personality", but as a thug and a Jerkass who torments people and has a personality like a dumpster fire.
  • At one point, Peter gets asked where he got the Iron Spider armor from, and he responds that he got it from his idol. This leads to confusion, as several boys complain that they wish that a cute idol made them cool armor (in Japan, an "Idol" is a type of cute pop star), before Peter clarifies that he meant a different kind of idol (a role model, someone he looks up to and deeply admires).
  • A positive example, from Peter's point of view, is that, in America, the laws against vigilantism are much laxer than in Japan, so a few characters, like Mirko, come to the conclusion that Peter's superior skill comes from doing vigilantism back when he lived in America. Peter goes along with this explanation that is technically right.
• Curb-Stomp Battle: Oh so many during the Sports Festival tournament matches.
  • As in canon, Bakugo easily beats Tokoyami, thanks to his explosions being a perfect counter to Dark Shadow.
  • Shoto flash-freezes Setsuna before she can split apart.
  • Shinso tries to goad Sato into falling under his brainwashing by insulting him. Instead, Sato just chows down on some sugar, activates his Quirk, and immediately body-slams Shinso out of the ring.
  • Ibara overwhelms Momo with her vines and tosses her out of the ring before Momo can make more than one weapon. Likewise, she does the same to Tsuyu in the next round.
  • Despite his best efforts, Sato isn't able to land a single hit on Peter before the Wall-Crawler judo-throws him out of the ring.
  • When Peter and Bakugo fight for first place in the Tournament Arc, Bakugo tries and fails to overwhelm Peter, expending all of his most powerful attacks on Peter before Peter nearly cripples him into submission with two hits. He doesn't even use his web-shooters, having run out of fluid in his previous fight. It does not take long for his teachers and classmates to figure out that Peter is purposefully prolonging the fight just to make a point.
  • Later, during the Hero Killer's arc, Peter and Izuku vs Stain. Catching him by surprise, while he's still recovering from his recent battle with Yoroi Musha, the Hero-Killer stands no chance, and his efforts to fight back only earn him a much more severe beating.
• Curb Stomp Cushion: Yoroi Musha vs Stain. While the battle is very intense and challenging for both fighters, Musha ends relatively fine, while the villain ends with serious injuries and is forced to escape.
• Cut Lex Luthor a Check: Power Loader and Mei both comment that some of the stuff in the Iron Spider armor could make the creator very rich, not knowing that Tony Stark did not become rich based on this technology, but rather became richer.
• Dark and Troubled Past:
  • Mt. Lady's musings about ill-timed Quirks and foster care strongly hint that her own family threw her away for having a troublesome power, leading her to be lost in the Department of Child Disservices.
  • Peter had the canonical death of Uncle Ben in his backstory, not to mention that in order to arrive in this new world, he had to literally die.
• Death by Adaptation:
  • The Nomu, in canon, got captured at the end of the USJ arc. Here, in order to save Peter, Momo sticks a box containing a thermite charge on the back of its neck, killing it nearly instantly.
  • Mirko meets her end when Overhaul absorbs her in chapter 59.
• Death Seeker: Mirko accuses Peter of this, stating that Peter has no sense of forethought or survival instinct when it comes to life-or-death situations. Considering everything Peter has been through, he starts thinking that she might have a point and questions his own sanity on the way home.
• Deliberate Values Dissonance: The people of the MHA world constantly praise Bakugo because they either think he is awesome (most everybody else) or are too scared of him (poor Izuku Midoriya), in spite of his crude, rude, and antagonistic behavior to many people, and only occasionally do people call him out or reprimand him for that behavior. Peter is an exception, having been raised on American anti-bullying culture (and having been bullied himself), and doesn't believe Bakugo deserves to be at UA.
• Didn't See That Coming:
  • Even All for One is caught off-guard when Kurogiri informs him that the Noumu created specifically to kill All Might was killed not by the Number One hero, but by the UA students before All Might even showed up.
  • When Monoma tries to copy Peter's abilities during the Sports Festival, he's shocked to find that Peter's Quirk simply can't be copied.
• Dies Differently in Adaptation: Native is killed by Stain while Iida is Forced to Watch.
• Different States of America: Having looked into the differences between MCU!Earth and MHA! Earth, Karen divulges to Peter that this Earth's United States of America has 53 states instead of 50, the US including Puerto Rico, the Bahamas, and the Virgin Islands.
• Early-Bird Cameo: While they don't physically appear, Inasa and Camie show up in a social media feed commenting on the Sports Festival.
• Embarrassing Nickname: After easily getting first place in the Hero Course practical entrance exam, Peter earns the nickname 'Ace' courtesy of Kirishima, which the wall-crawler finds incredibly embarrassing. He's downright mortified when he finds out that rumors of the 'First Year Phenom' have begun circulating throughout U.A..
• Entertainingly Wrong: Both Endeavor and Eraser Head are convinced that Peter is All Might's apprentice, due to their similar powers, both being seen as The Ace, and some misunderstood comments or behaviors from All Might. Neither has pieced together that Peter has no connection to the No. 1 hero, and that All Might is actually training Izuku Midoriya, who is considered the dead last in his class.
• Entitled Bastard: Bakugo, like in canon, is this. He didn't score first place in the entrance exam like in canon because Peter did, but he thinks it's a simple matter of showing him up eventually.
  • Despite his father's efforts, Shoto is not this, deliberately incinerating files that Endeavor tried to give him as a way of showing his contempt.
• Everyone Has Standards: While Bakugo is a Jerkass who's openly rude to Peter at every turn, and has the intention of beating him to become #1; he certainly didn't expect to see him being pummeled to near-death by the Nomu, nor getting taken hostage by Shigaraki during the USJ arc.
• Everyone Is a Super: One of the basic premises for the MHA universe is that almost everyone on the planet has a 'Quirk', a.k.a. a superpower. This lets Peter blend his own powers right in and no one questions it.
• Experienced Protagonist: What makes Peter a cut above everyone else in Class 1-A, aside from his diverse power-set, is that he has far more experience than any of them. He's already tangled with common criminals, basic Samaritan work helping citizens in New York, fought several of the Avengers, defeated the Shocker and the Vulture, and then fought Thanos alongside Iron Man, Doctor Strange, and the Guardians of the Galaxy. Everyone else in his class, meanwhile, is still a novice despite whatever powers they have.
• Expy: Detective-turned-manga-author Araki Hyu is two in one for Dr. Gregory House and Rohan Kishibe. He's a grouchy old man who walks with a limp and who's only interested in handling interesting cases for the authorities like House, and he uses whatever he learns when using his Quirk as inspiration for his manga like Rohan. His Quirk that allows him to read a person's memories is also based on Rohan's stand ability.
• Fighting Clown: He wouldn't be Spider-Man if he didn't crack jokes and puns in the middle of a fight, and he is no different here. Shoto even questions if he ever shuts up.
  • Aizawa takes an instant dislike to Peter because of this, seeing him as someone who could be way more effective if he just focused on doing the job instead of making cornball jokes. Heroes who do this are also something of a Berserk Button for Aizawa, considering he once expelled an entire class for not taking things seriously enough on day one.
• Forced to Watch: Iida, paralyzed by Stain's quirk, can only watch in horror while the villain kills Native.
• Foreign Exchange Student: Peter and Pony are this at UA, both from America and they stand out a good deal because of their non-Japanese looks. It's also part of the title. Though technically Peter doesn't count, as he's not from an American school (in this universe, that is).
• Foreign-Language Tirade: Even after becoming fluent in Japanese, Peter tends to switch back to English when he's freaked out, such as when he notices how Izuku destroyed his arm and legs after destroying the zero point robot during the entrance exam.
• Genius Bruiser: A number of students in 1-A qualify
  • Peter created his web-shooters himself and has noted that he finds math and science incredibly easy. Combined with his powers, he fits this bill very well.
  • Bakugo is also this; Aizawa even calls him a "genius berserker" in his inner monologue.
  • Momo is on her way to becoming this, if she hasn't achieved it already
• Giant Woman: Mt. Lady, AKA Yu Takeyama, is this when using her Quirk. It offers her a great deal of power and a very dedicated and... niche fanbase.
• Greeting Gesture Confusion: Peter is still figuring out bowing in Japan and how deeply he needs to do it in appropriate social situations. He also gets confused as to what suffixes he's supposed to add to names, or which name it's appropriate to hand out to people (should he be known as "Peter" or "Parker"?)
• Heads-Up Display: The Iron-Spider suit does this for Peter, helping him pick out the most optimal paths to get to targets that it also conveniently marks for him.
• Healing Hands: All for One is able to combine multiple Quirks such as Regeneration and Bone Regrowth to heal Shigaraki after the younger villain takes the full force of Izuku's Detroit Smash during the USJ attack.
• Hey, You!: Like in canon, Bakugo does this to all his classmates. To Peter especially, he either calls him "Redshirt" or "American" in rude tones. But also like canon, if he refers to others by their actual name, it's a sign of respect. A big example of this happens in Chapter 13, where Bakugo openly refers to Peter's last name in a conversation with his father, and Masaru takes note of that. By the time of the Sports Festival tournament, he starts calling Momo by her last name as well, which floors Izuku.
• Heroic BSoD:
  • Neither Peter nor Bakugou is in a nice place in the aftermath of their fight, but Katsuki gets it a hell of a lot worse — best way to describe his attitude is him having had his soul removed. Even when he labels both Izuku and All Might as liars for trying to reassure him with facts that go against what he believes of them, Midoriya is actually somewhat scared when, aside from the customary "stupid Deku", Kacchan flat-out pleads (usage of "please" included) him, in tears, to just go away. Heck, one scene even sees Bakugou staring at a drop of his sweat he holds in his palm in a way his train of thought describes as "feeling useless for all of his power" but the regular narration describes as "wondering whether or not to use that little drop of nitro to blow his brains out".
  • After his obsession for revenge against Stain gets Native killed, Iida starts wondering if Stain was right about him being unworthy of being a hero and seriously considers withdrawing from UA.
• Hidden Depths: Even though Hatsume is overzealous when it comes to Support gear, she's actually more concerned with the heroes who use them. She tells Peter that Support gear is just that: support. In the end, it's the hero who makes something of that gear.
• Hidden in Plain Sight: Thanks to Peter better fitting the mold for All Might's potential successor and having a status as Class 1-A's "dead last", neither Aizawa nor Endeavor suspect Izuku of being All Might's successor.
• History Repeats: A contributing factor in Endeavor's growing dislike towards Peter is that the parallels between him and All Might are almost identical. All Might was an American-themed hero who took the hero community by storm, coming to the top from out of nowhere and getting in Endeavor's way of being No. 1. Now Shoto has everything set to be the pinnacle of his class and generation, and some unknown foreigner from America comes out of nowhere and takes the crown.
• Hoist by His Own Petard: Bakugo thinks that by pushing Peter's buttons and trying to enrage him for their Tournament Arc battle, Peter will become sloppy and give Bakugo the right opening to win, as well as make himself look more impressive when he defeats Peter in-front of everybody when Peter is giving his all. What follows is a Curb-Stomp Battle that leaves him almost maimed, Peter exhausting him throughout the fight before taking him out in two hits and nearly hitting him with a third that made All Might flinch.
• Hostile Weather: Aizawa, with good reason, considers natural disasters as a much bigger challenge than any villain, being powerful, chaotic, affecting large areas at once, and forcing heroes' abilities to the max.
• The Illegal: Peter, seeing as he didn't exist in the MHA universe until he suddenly did. Thankfully, a cop with connections helped correct that through not-entirely-legal means.
• Illegal Guardian: A positive example in Yu. She doesn't necessarily adopt Peter in fully legal ways, seeing as he legally doesn't exist, but she sees that he has nowhere to go and steps up to take him in and give him a home.
• In Spite of a Nail:
  • Izuku still gets chosen by All Might to be his successor and receives One for All.
  • Despite not being in Hosu during the Noumus's attack and Iida's disastrous battle with Stain, Izuku still ends facing and defeating the Hero Killer. The circumstances are still different, with Izuku teaming up with Peter, and ambushing Stain in his own hideout.
• Ineffectual Loner: Both Bakugo and Todoroki during the War of the Flags at the Sports Festival. Thanks to their single-minded need to beat Peter, they simply gun straight for him instead of trying to work with their team. While they do manage to hold their own and take three bands from the Red Team, Bakugo winds up costing his team two silver bands in the process. Aizawa muses that if the two of them could have put their egos aside and actually worked with their teammates, then the Blue Team would have won by a landslide instead of the two teams tying, allowing Peter to beat Tenya in the tiebreaker round, which costs the Blue Team the match.
• Invincible Hero: All Might is this to the world at large.
• It's All My Fault: All Might understandably blames himself for using up his time limit on the way to work and consequently not being at USJ when the League of Villains attack the students, which results in Peter nearly being killed by Shigaraki and the Noumu and the students who witnessed it being left thoroughly shaken. The fact that he was the target of the attack to begin with just adds to his guilt.
• It's Personal: Shigaraki develops one hell of a grudge against a number of the students of class 1A during the USJ Attack. He especially wants to kill Peter and Momo for respectively stalling and killing the Noumu made to kill All Might and Izuku for knocking his teeth out and destroying his father's hand.
• Jerkass Has a Point:
  • Endeavor warns his son that he can't simply go into the Sports Festival with what he currently has and expect to win and that he needs to better prepare for what lies ahead. Shoto ends up completely disregarding his father out of spite, and acknowledging that he was right after seeing Peter dominate the Obstacle Race portion of the Sports Festival is an insanely bitter pill for him to swallow.
  • While Mirko's Brutal Honesty borders on indifferently cruel, she makes a good point that Peter's complete lack of personal ambition and tendency to "react" instead of "act" could have massive consequences in the long run.
• Jerk Jock: What Peter sees Bakugo as, and it's not totally incorrect.
• Jerk with a Heart of Gold: Yu is rather vain and more than a bit of a Glory Seeker, but she genuinely cares for Peter like an older sister would and wants to help him because it's the right thing to do.
• Karma Houdini: Peter thinks Bakugo is this. Coming from a world without quirks and being raised to use his powers responsibly in a culture that frowns upon bullying, he is quick to write Bakugo off as an annoyance when he tries throwing his weight around. His views grow into full-on Jerkass when Bakugo continually abuses his powers for petty fullfillments and trying to provoke him with everyone looking the other way with the misguided belief that he will eventually grow out of it. It is not until Bakugo mercilessly beats Pony in their Tournament fight and then arrogantly accuses the Avengers as not being real heroes because they lost does Peter's annoyance boil over into seething hatred, nearly killing him in a Curb-Stomp Battle in what he saw as a Karma Houdini Warranty to prove a point.
• Karmic Jackpot: The reason why Edgeshot chose Izuku for his Hero Agency was because that in spite of the Sports Festival being a competition, Izuku altruistically prioritized his opponent's well-being over his own, destroying his own body and prolonging the fight instead of winning it because Shoto Todoroki needed his help.
• Lack of Empathy: Unlike the rest of 1-A, and (apparently) most of 1-B Class, Bakugo couldn't care less about Stain almost killing Iida, and doesn't see why it should concern him. Pony calls him out on this attitude, with Bakugo doing his best to ignore her.
• Laser-Guided Karma: In their Sports Festival match, Peter humiliates Bakugo by tiring him out before completely curb-stomping him, having been driven to do it due to Bakugo's attitude and near-villainous actions and nearly killing (or at the very least, permanently crippling) him in the process. The U.A. Staff noticed this and fully intended to punish Peter for it. Recognizing that Peter isn't the type of person who would do such things unprovoked, All Might volunteers to talk to him first, and Peter relents and admits that he deserves the reprimanding after he had cooled down.
• Late-Arrival Spoiler: Thanos wins and uses the Infinity Stones to murder half of the MCU, including Peter. Given that the story opens immediately after that, it's impossible not to be spoiled.
• Lightning Bruiser: Peter's superhuman agility mixed with his strength make him an absolute terror in close combat. When he and Todoroki clash during the Battle Trial, Peter is able to dodge every blast of ice Todoroki sends his way and easily destroys any walls that his classmate tries to put in his way.
  It was like trying to hold down the breeze from a hurricane. Faster than anything had the right to be and far stronger than you could ever imagine.
• Logical Weakness:
  • As Shoji points out during the Heroes vs. Villains exercise, while his Quirk allows him to pick up sounds from far away, he generally has to stay still to get an accurate idea of the sounds' location. If he tries to track something on the move, his own movements turn into distracting background noise.
  • Given prep time, Momo's Creation Quirk can make her a nightmare of an opponent against anyone. However, since she needs a bit of time to create anything complex, she can be easily beaten if her opponent can simply overwhelm her before she can use her Quirk, as Ibara shows during their match at the Sports Festival.
  • Peter is eventually revealed to be able to get drunk on chocolate. Spiders get drunk on caffeine, after all.
• Lost in Translation: Peter didn't speak even a lick of Japanese when he is transported to MHA's version of Japan, so a lot of this occurred at first. Taking into account that he's still only been there for under a year and he's also from another dimension, it's very impressive that he's able to communicate with everyone as well as he is now, even with the occasional lapse back into English.
• Mama Bear:
  • Beru Asui, who's not afraid to let All Might know just how unhappy she is with the fact that he wasn't present when villains attacked USJ and tried to kill the class 1A students, including her daughter.
  • Also Maiya Yaoyarozu, who straight-up kills the terrorists threatening Momo during the I-Island incident.
• Mind Probe: Araki's Quirk, Dream Drawer, allows him to read a person's memories by touching them and then expertly sketching them out. The usefulness of it has made him a highly valuable asset to the police department.
• The Bet: Mirko and Edgeshot hedged a bet on Peter's Spider-Sense.
• Mundane Utility: Part of Izuku's training with Edgeshot is learning how to use his abilities for more mundane purposes as a better means of learning control, turning his own fingers into chopsticks for eating as an example.
• Mythology Gag:
  • When listing the other hero schools around the world that rival U.A., Yu mentions the Xavier Private Charter School in Boston, U.S.A..
  • Sato's match against Shinso in the tournament portion of the Sports Festival plays out pretty much exactly like the Hulk's beatdown against Loki. Sato Hulks out and proceeds to bodyslam Shinso so hard into the ground, that all Shinso can do is lay on the ground in pain
    Sato: Puny gen ed.
  • When mulling over an official name for his Spider-Sense, Peter briefly considers calling it his Peter Tingle, only to quickly decide it sounds stupid.
  • Peter's powers being identified as a mutation-type Quirk is, (in what's likely a case of Accidentally-Correct Writing) one towards the comics incarnation of Spidey, who is considered a mutate.
• Never My Fault: When he thinks he won against Peter in the Sports Festival, Bakugo goes on a rant about how every loss and perceived moment of weakness he had suffered since becoming a student at U.A. are all either due to circumstances beyond his control or because of the inadequacies of others. Even after All Might stops Peter from beating Bakugo to death after rendering him unable to fight, Bakugo sees it less like him losing a fair fight against Peter and more like All Might swooping in to rescue him from a situation he shouldn't need saving from.
  Katsuki Bakugo: There... I'm the one... who is the one closest to All Might! Not you! You lost before! Back then when you got yourself caught! You brought trouble for everyone back then! Deku fucked up his body! Yaoyorozu got blood on her hands! Redhair became a fucking wimp! But me?! I've only lost by some stupid rules back against Deku in that stupid battle! People got in my damn way during the race and you all ganged up on me during the War! But now! Everyone knows that I will be the greatest! The strongest! I'm going to be the Ace here! Not you!
• "No. Just… No" Reaction: Played for Drama. This is Peter's initial reaction when he finds undeniable proof that he died on Titan and is stranded in an alternate reality where his friends and family don't exist. It quickly turns into Rapid-Fire "No!" and finally a full breakdown.
• No Sense of Personal Space: Mei, much to Peter's discomfort.
• No-Sell: During the Provisional License Exam, Ochako uses her quirk to hit Endeavor (dressed as a villain for the exam) with a plank. That just pisses him off, to her horror.
• Normal Fish in a Tiny Pond: Peter, in his world, is an inexperienced street-level hero whose power isn't that great against some of the things the Avengers go up against, such as evil AIs, alien invasions by Norse Gods, or worse. When put into his new world, he's (compared to his classmates who aren't allowed to be vigilantes) extremely experienced and his power is a terrifying combination of wall-crawling, minor precognition, and enhanced human strength and agility.
• The Nothing After Death: One of Araki's drawings of Peter's memories is the moment after Peter was turned to dust after Thanos's snap, which is depicted as an entirely black page. Police Chief Fukuda is left deeply unsettled when he considers that this is what the page implies.
• The Obi-Wan: As per canon, All Might is this to Izuku. Peter constantly refers to and asks himself, "What would Mister Stark do?"
• Odd Friendship: It's a completely one-sided one, but Peter finds it bizarre that Izuku refers to Bakugo with the "-chan" suffix and that he considers someone who repeatedly bullies and insults him as a friend.
• O.O.C. Is Serious Business: In spite of his Dark and Troubled Past, Peter still takes the time to make jokes and quips whenever he's in a rough situation. Those with quiet and stoic personalities like Aizawa think he does not take the dire situations he's in seriously enough, but Aizawa can only watch with chilled awe when Peter absolutely decimates Bakugo in the Tournament Arc on their one-on-one fight, dodging everything Bakugo throws at him before nearly crippling him in two hits without uttering a single word. It's so worrisome that All Might (who sensed something was wrong and tried having the fight postponed beforehand) had to step in before Peter renders Bakugo permanently crippled out of hatred for his fellow classmate.
• Overshadowed by Awesome:
  • Momo's opinion of her own Quirk. While she acknowledges that her Creation is one of the most versatile Quirks in history, she feels that being able to make things is a bit lackluster, compared to the powersets of some of her classmates, such as Peter, Todoroki, or Ibara.
  • In the Provisional License Exam, this is part of the reason why Kendou failed by one point.
• Papa Wolf: Wolfram shoots Fuyumi, enraging Shouto, then threatens to kill her while taunting him. Unfortunately for Wolfram, Endeavour was Right Behind Him.
• Pervert Revenge Mode: During the Obstacle Race, several girls from other classes beat up Mineta for his many lecherous acts.
• Point of Divergence:
  • It is implied that unlike in Avengers: Infinity War, where Thanos makes his Badass Fingersnap on Earth when canon!Spider-Man was still on Titan, fanfic!Spider-Man was there when he snapped him out of existence, giving Peter a negative psychological reaction whenever he hears somebody snapping their fingers and him indirectly quoting Thanos^note Saying "For him to feel so desperately that he was right, only to lose, all the same" after beating Bakugo in the Tournament Arc. when he could not have possibly heard it.
  • During the first lesson with All Might, Peter is partnered with Momo, giving the latter experience in a combat role.
    • He also shares his web formula with her, which she starts integrating as part of her arsenal.
  • The whole USJ Attack. Some of them are:
    • With Mineta not being part of Class 1-A, his position with Tsuyu and Izuku is replaced by Kaminari, making the three of them able to escape faster, simply by throwing the electric boy into the water.
    • Peter jumps in to stall the Noumu so his classmates can rescue Aizawa and gets seriously injured for it.
    • Rather than getting captured, the Noumu is killed by Momo via thermite charge.
  • Because of a combination of Aizawa's injuries at the USJ causing him to rest instead of doing the post-USJ visits with All Might and how much more traumatizing the event was for his students, he comes up with a completely different scenario for the second task of the Sports Festival that winds up being used.
  • Thanks to Peter's help, Izuku figures out how to use Full Cowl before he starts his training with Gran Torino.
  • Because of the boosts in their confidence (from having another English-speaking friend in Pony's case, and getting battlefield experience in Momo's), Pony and Momo take second and third place, respectively, in the obstacle course at the Sports Festival, after Peter. Iida comes in fourth, Izuku fifth, Bakugo sixth, and Todoroki seventh.
  • Thanks to figuring out how to use Full Cowl before the Sports Festival, Izuku puts up a much better fight against Todoroki in the tournament phase, to the point that he actually manages to beat him, albeit at the cost of injuring himself too much to continue to the semi-finals. He also ends the fight far less injured than he would have otherwise, having broken all of the fingers on his right hand and one of his legs as opposed to thoroughly destroying his right arm, thus avoiding the scarring he got from canon.
  • The winners of Sports Festival wind up being quite different from canon with Izuku and Ibara coming in third place, Bakugo in second, and Peter taking first place.
  • Because Izuku learned how to use Full Cowling before meeting Gran Torino and showed off his new abilities at the Sports Festival, he doesn't intern under him like canon and instead interns under Edgeshot. Also, Uraraka and Momo choose different heroes for their internships; Uraraka gets the Wild Wild Pussycats, as she wants to specialize in rescue operations, and Momo chooses Yoroi Musha, to improve her battle proficiency.
  • As stated above, several pro-heroes get to appear much sooner than in canon, many of them also getting expanded roles. Among the main examples are Mirko, who becomes Peter's mentor, and Gang Orca, as Katsuki and Pony's.
  • Because of the different internships, Midoriya isn't in Hosu during the Nomus' attack, and Todoroki sticks to working with his father's sidekicks, so none of them arrives to rescue Iida and Native from Stain. Instead, Yoroi Musha and Momo arrive in the nick of time, rescuing Iida, but not Native.
  • Because of all the life-or-death situations they'd been involved, 1-A's final exam is changed from Battles 2-on-1 Against A Teacher to Hero Teams Attending Emergencies, with several students teaming up to face a particular emergency (Hostage Situation, Capturing Villains, Natural Disaster) in order to test both Teamwork and Individual Performance instead of just Battle Abilities. It's later revealed that 1-B's finals were similar, with the emergency simulations being Bomb Retrieval and Disarming, Infiltration of a Villain Lair, and Crime Scene Investigation.
  • Due to the USJ Nomu being killed by students, Dabi and Toga aren't too impressed with Shigaraki, and they get an instant, mutual dislike of him. Combined with Stain being forced to escape and later captured instead of his canon last stand in Hosu (depriving Toga and Dabi of an important motivation), they don't join The League of Villains.
• Politically Incorrect Hero: Of the nominal variety with Bakugo. He expresses disdain for Peter due to him being American, though his insults toward him involving this are later rooted in jealousy rather than outright prejudice.
  • While it's more downplayed compared to Bakugo, there are some students who underestimate Peter due to him being an American exchange student. After his performance at the entrance exams, this mindset stops.
  • When Peter comments on Iida's attitude in the written test of the entrance exam, Iida calls him a foreigner and tells him to speak their language or to leave. He later apologizes for this, and Peter brushes it off as test nerves talking.
  • In one of the omakes, Kendo expresses confusion that Setsuna hitting on Peter didn't get a stronger reaction. Tsunotori calls her out on it, saying that assuming that Peter would fit into the "American" stereotype – loud and outgoing – is doing the boy a disservice since he's not like that at all.
  • Endeavour dislikes that Peter managed to beat Shoto not just once, but twice, and one of the ways that he insults Peter is by pointing out that he's a foreigner. It goes deeper than this, though, as he sees history repeating itself with an American-themed hero beating a member of his family from out of nowhere, just like All Might did to him.
• Popcultural Osmosis Failure: To Peter's dismay, Star Wars has faded to obscurity in the MHA universe.
• Power Creep, Power Seep: Back in the MCU, Spider-Man is a powerful hero, but heavily inexperienced compared to the various veterans of his world who have been saving lives and stopping global crises for over a decade at this point. When put in Class 1-A, he becomes The Ace of the class, having the most experience and an overall powerset that blows most of theirs out of the water.
• Powered Armor: This Peter comes from the ending of Infinity War where he had the Iron-Spider suit on. It has a ton of features like nanobots to form it up, armor plating, and robotic spider-legs that he can use to tear through things. It also looks cool. Unfortunately, the armor is destroyed by the Noumu during the USJ attack.
• Pragmatic Hero: Mirko's entire hero philosophy is centered around this, her lonewolf methods based around the risk assessment that comes with having a team and Peter's entire internship being based around trying to break him out of his more idealistic notions of heroism. This is deconstructed when Peter and Izuku catch the Hero Killer, as she ends his internship then and there because he risked his life and by extension her reputation for going after him when she forbade it.
• Properly Paranoid: Aizawa sees all the oddness in Peter's powers, skills, and background, and is very quick to be suspicious of him. Given that MHA has a traitor storyline in canon, he's right to be suspicious, even if he is looking into the wrong person.
• Psychological Projection: During Bakugo's inner monologue in Chapter 6, he rants and accuses Peter of a number of things that are easily found in his own flaws. He refers to him as Dumb Muscle, but Bakugo himself is guilty of being one due to letting his own temper override his common sense. He also thinks of Peter being ignorant of Japanese culture for the small habit of switching between languages, while his entire personality doesn't follow the Japanese values at times.
• Pyrrhic Victory:
  • While Izuku manages to defeat Todoroki during the Sports Festival tournament, he breaks all of the fingers on his right hand and one of his legs in the process, leaving him in no condition to continue on to the semifinals even with Recovery Girl's treatment.
  • Peter's victory over Bakugo in the final match of the Sports Festival is a hollow one. While Peter wins and successfully shatters Bakugo's massive ego, he lets his rage overcome him at the very end and very nearly maims the other boy before All Might steps in to end the match. While the vast majority of watchers don't notice what happened due to All Might's sudden appearance, Peter is left horrified by the fact that he lost control of himself in a fight against a fellow student, even if that student is Bakugo.
  • While Edgeshot has nothing but praise to give Izuku when he and Peter catch the Hero Killer, Mirko ends Peter's internship early because of it, seeing his tendency to make everything his responsibility a result of an unchecked ego and the risk of his death having put her good reputation on the line.
• Readings Are Off the Scale: During the Quirk evaluation test, Peter's grip strength registers as 999.99 kg. Aizawa's phone shows that he actually gripped the measuring device so hard that he broke it. Similarly, Yaoyorozu breaks hers, although she creates a clamp to accomplish this.
• The Real Heroes: In Chapter 34, Pony gives a brief filibuster on how firefighters deserve the same level of admiration and praise as pro-heroes after she and Bakugo saved civilians from a building fire the previous day, having experienced and barely got out of a situation that firefighters are expected to endure all the time.
• Right for the Wrong Reasons:
  • Aizawa was right to assume that All Might has a favorable eye on one of the students in Class 1-A, since he spotted the latter from afar during the Quirk Apprehension test. He thought it was Peter due to the similarities of their power-sets, and was a bit surprised when All Might mentions Midoriya instead.
  • Played for Laughs in Chapter 13, where Masaru believes that Peter is someone "important" to Bakugo when his son openly refers to the former's last name instead of the usual "nicknames". He thought that his son meant in a sense of being "close friends" until Bakugo stated otherwise.
  • Much like Aizawa, Endeavor is aware that All Might is training someone in Class 1-A and assumes it's Peter for the same reasons and being associated with the American culture.
• Screw the Rules, I'm Doing What's Right!:
  • After learning from Araki that Peter is a scared teenager stranded in an alternate reality after being killed by Thanos, Police Chief Botan Fukuda arranges to have a fake visa and documentation made for him, while Yu agrees to become Peter's guardian. They both lampshade that what they're doing is pretty damn illegal, which is especially notable considering their careers, but they decide that it's the right thing to do anyway given Peter's circumstances.
  • After being forbidden to continue searching for Stain, Izuku and Peter, separately, decide to continue searching and go catch the villain anyway, as they have solid leads on his possible location, and can't let him to escape and attack other heroes while waiting for the right permissions.
• Secret Test of Character: Once Edgeshot tells Izuku that they'll no longer get involved in the Stain's search due to jurisdictional and legal aspects, he leaves the agency and waits outside, expecting Izuku to go find Stain himself anyway, which happens soon enough. Edgeshot fully approves as it's another proof of Izuku's heroic nature. He still follows the boy from a distance in case he needs assistance later.
• Seinfeldian Conversation: While awaiting the tournament phase of the Sports Festival, Sato questions whether or not Present Mic has a mute button on his hero costume. Pretty soon, half of the table joins in the debate.
• Single-Stroke Battle: The tiebreaker match between Peter and Iida after the War of the Flags. Iida immediately uses his Recipro Burst to push Peter out of the ring before his classmate can react. Peter manages to recover just enough in midair to fire a web at Iida and pull him out of the ring as well, where Iida hits the ground first. The whole thing happens so fast that Present Mic compares it to a duel between two samurai ending in an instant.
• Ship Sinking: Sadly, when Pony asks out Peter, he reveals he only sees her as a friend. It's confirmed by co-author LD that this was deliberate, as main author Zaru didn't have any plans for her beyond being a Satellite Love Interest, so he sunk the ship to force her character to be fleshed out more outside of Peter.invoked
• Shout-Out:
  • Peter refers to the faux villain robots used in the U.A. entrance exam as WALL•Es.
  • The Quirks and appearances of the three students who beat up Mineta during the Obstacle Race for his pervy acts in school are references to Kirara, Lust, and Jolyne Kujoh.
  • Peter's early string of victories at the start of U.A. is similar to that of the titular character from Inuyasha.
  • Peter's near-lethal final attack towards Bakugo mirrors to the scene of Kenshin nearly breaking his vow when push to a Rage Breaking Point. For bonus points? The characters who manage to provoke them are both blond-haired attention whores.
  • In Chapter 26, Peter mutters the line, "Summer rains, can never predict them".
• Show Within a Show: Araki uses the knowledge he gleaned from Peter's memories to create his new manga Arachnaphobia, which follows the adventures of a boy born from a spider and his two companions, a tin man and a wizard as they travel across a post-apocalyptic world. Peter finds himself a little too uncomfortable to read it, given that he knows its source material (and that the characters are based on himself, Iron Man, and Doctor Strange). Other students at UA, such as Itsuka, like to read it though.
• Shrinking Violet: Pony is much more shy and withdrawn when Peter first meets her. She quickly comes out of her shell after she and Peter bond over their aspirations to become heroes.
• Sir Swears-a-Lot: Anytime Bakugo opens his mouth, you can be sure there's gonna be plenty of cursing.
• The Sleepless: Due to his spider physiology, Peter's body can get by on one or two hours of sleep a night, which is a bit of Truth in Television as spiders don't actually sleep, but instead enter a sort of 'rest mode'. This comes in handy with helping him avoid his night terrors, but the downside is that he cannot keep this sleep pattern up indefinitely. His brain can only handle it for so long before he crashes hard. After the USJ Attack, he winds up sleeping for three days to recover.
• So Proud of You:
  • Yu frequently expresses great pride in Peter's accomplishments, such as getting the highest scores on the Entrance Exams as well as acing the Obstacle Race in the Sports Festival.
  • While more subdued and in mental musing, Aizawa was amazed by Izuku finally managing to get his self-destructive abilities under control.
• Spider-Sense: The Trope Namer himself. Peter has only been shown using it a handful of times to avoid most of an explosion and to catch a ball he had no way of knowing was thrown at him, but it is apparent he has it all the same.
  • As of the third round of the Sports Festival, he is finally aware of its existence too.
• Spit Take: Power Loader made the mistake of drinking from his thermos when Peter explains the power output of the Arc Reactor within his suit. Cue the water coming back out.
  • On a quick trip to visit Mirko, All Might is asked by the heroine what his interest is in Peter. Asking if it's because Peter is secretly his bastard child. Cue the spit, and All Might pointing out that the math for such a thing doesn't work out.
• Spotting the Thread: Aizawa, on seeing the Iron Spider suit and hearing Peter's backstory, knows that there are too many things that just don't add up, but he first gets suspicious when he hears that even though Peter is from Queens, he was sent to live with Mt. Lady, who is not biologically related to him and lives on the opposite side of the planet in a country where he doesn't speak the primary language.
• Starting a New Life: The whole premise is that Peter is taking all of the experience he gained in his home dimension and is starting anew in MHA!Japan.
• Statuesque Stunner: Yaoyorozu is easily the tallest girl in class 1A and Peter finds her so attractive that he thinks she makes Liz look average by comparison.
• Stealth Insult: In the Arachnobia Manga by Araki, Peter Quill is depicted as an anthropomorphic Porcupine person dressed as a cowboy. His quills "countless". In other words, Starlord is a prick.
• Sticky Bomb: Momo uses some of Peter's webbing to stick a thermite bomb to the back of the Noumu's neck, so that it can't remove it before it detonates and kills it.
• Strong and Skilled: Being able to lift a car and crush it with relative ease while also preferring a more acrobatic and skill-based fighting style, Peter fits this trope well.
• Superpower Lottery: While Peter had already won it back in the MCU, the insane usefulness of his powerset is much more apparent when compared to his classmates, which is even lampshaded by Kirishima. In a world where a person is lucky to have a Quirk with multiple applications without any serious drawbacks to compensate, Peter has Super-Strength, Super-Reflexes, and stamina, Wall Crawling, and perhaps most useful of all, his Spider-Sense.
• Talking through Technique: During the Tournament Arc, Edgeshot has already considered putting Peter down as a potential intern for his Hero Agency. When Gang Orca comes in and asks him what he thinks about the contestants, Edgeshot tries keeping Peter out of the conversation as much as possible, in hopes of keeping Gang Orca from getting the same idea, only for Gang Orca to immediately guess that Edgeshot has put Peter down as a candidate, and then points out that it's the same for every other hero watching.
• The Real Heroes: Gang Orca's agency cooperates with the Fire Department doing rescue and assistance work at a burning building, with the firefighters keeping up with the heroes.
• The Tease: Setsuna's very first action upon meeting Peter is to blatantly check him out and flirt with him, only to quickly reveal that she's just messing around before properly introducing herself. Later during lunch, Peter notices her staring at him with a look that he likens to a cat wanting to play with a mouse.
• Three Laws-Compliant: Karen mentions repeatedly that her programming involves the "Ultron Safeguard", a list of rules and parameters set in place to keep her from going rogue in the same way that Ultron did.
• Throw the Dog a Bone: Peter Parker canonically has to struggle through piles of crap shoveled on crap piled on him, as the Multiverse seems to enjoy torturing him with the goal to make him believe Heroism isn't a career option for him. In the Quirkverse, not only are there people who do believe he can be a Hero, they believe he will be a great one.
• To Be Lawful or Good: Once they learn about Stain almost killing Iida, Izuku and Peter, separately, start working to locate the criminal; Izuku does it on an official manner along with Edgeshot (until the latter points out the legal and jurisdictional issues), while Peter does it unofficially with Karen's help (as Mirko decided to stay out of the investigation). Once they find the most possible hideout, both Izuku and Peter go there despite their mentors' official disapproval, and, by mere coincidence, arrive around the same time and start working together.
  • It's shown that Edgeshot actually expected Izuku to disobey him and go after Stain anyway, showing that, while he officially can't approve of his pupil's actions, he still agrees on being 'Good' over 'Lawful'.
• Tragic Keepsake: Both the Karen AI and the Iron Spider armor are this for Peter, as they are the last remnants he has of both his mentor and his old world as a whole. When the armor gets destroyed by the Nomu, he becomes desperate to fix it.
• Tranquil Fury: After Bakugo unwittingly insults Iron Man and the other heroes who failed to stop Thanos, Peter, having finally reached his limit with Bakugo's self-righteous Jerkassery, goes into a state of deathly calm silence. Once the final match of the Sports Festival begins, he proceeds to outright demolish the other boy.
• Trapped in Another World: The premise of the story itself. Peter is trapped in the MHA world following Thanos wiping out half of the MCU universe and has no way of getting home.
• Trauma Button: Peter can't help but flinch at snapping fingers, although he doesn't understand why.
• Unknown Rival:
  • Peter has no idea that Bakugo is gunning for him, thinking he's merely a Jerkass (which, to be fair, he is that). He also has no idea of Todoroki's animosity towards him, other than that Todoroki keeps staring at him.
  • Momo is unaware that Pony considers her a rival for Peter's affection.
• Underestimating Badassery:
  • Many of the potential up-and-coming students at the beginning of the UA Entrance Exam write off Peter as a non-threat simply due to him being an American foreigner. It's only after witnessing him using the Iron Spider suit during the practical portion of the entrance exam that they clam up.
  • On separate occasions, both Bakugo and Todoroki believed that Peter wouldn't be as effective without the Iron Spider suit, and both were looking forward to wiping the floor with him at the UA Sports Festival. It's only after Peter scores first place in the obstacle race by a massive margin, that the realization kicks in.
  • Bakugo finds it funny that Pony thinks she has a chance against him. Not only does she manage to take him by surprise, she also very nearly beats him with a surprise chokehold during their match in the tournament portion of the Sports Festival; it's only through an extreme desperation move that Bakugo wins the match.
  • While most pro-heroes admire Peter's raw talent and Superpower Lottery, some of them think that Peter is a showoff who would be The Ace everyone thinks he is if he wasn't such a clown and a motormouth, unaware that it is Peter's way of coping with tense situations. Aizawa, in particular, thinks that he is arrogant and could be a liability because of this, his high stats being the one thing keeping Peter enrolled. Mirko thinks that he is completely lacking in ambition, something that is sabotaging his own future as well as making the rest of his classmates look stupid by comparison; downplayed in later chapters when Mirko realizes that Peter really is that good and that's why he has the time to quip and joke while fighting most enemies.
• Unstoppable Rage: After Peter thrashes Bakugo during the final match of the Sports Festival, Bakugo, barely able to so much as stand up, refuses to accept defeat, declaring once more that real heroes don't lose. This finally drives Peter over the edge as he launches himself at the other boy. It's only thanks to All Might stepping in at the last moment that Peter is stopped from seriously injuring Bakugo, if not outright killing him.
• Very Loosely Based on a True Story: Police consultant Araki Hyu is able to read memories and is currently a mangaka and is called in to look at Peter after the latter lands in the MHA world just to make sure he's not someone dangerous. Araki then goes on to write the manga Arachnophobia which, while a fantastically altered account of Peter's life, is uncomfortably close enough that Peter only reads the first issue.
• Villains Act, Heroes React: Discussed. During the Battle trial, when Mina comments on how the hero team is at a large disadvantage due to the villain team having time beforehand to prepare, Peter points out that's ultimately par for the course: Villains are usually the ones who make the plans and set the traps, while heroes have to react to those plans and stop the villains.
  • Mirko's biggest criticism of Parker is his complete and utter lack of personal initiative, citing his actions during the War of the Flags as Peter not thinking ahead and merely reacting to the opposing team and nearly losing the game as a result.
    • To drive the point home in Chapter 54, when Mirko happens across Eri and Overhaul. The scene begins very similar to the canon version, with Overhaul claiming to be her father and chalking Eri's odd behavior up to childishness. However, unlike Izuku and Mirio, Mirko sees straight through the ruse and nearly kicks Overhaul in half before saving Eri. Mirko saw an ambiguous situation, but through experience and instinct, took the initiative and (possibly) saved everyone a massive headache in the future.
• Vomit Discretion Shot: When Ochako loses her lunch during the entrance exams, Peter quickly looks away.
• Wham Episode: The USJ Attack. More so than in canon, even, considering Peter's extensive injuries and how Shigaraki's Quirk brings up past trauma from Infinity War. Not to mention that the Iron Spider armor is now destroyed.
• What the Hell, Hero?: Izuku gives one to Shoto about his refusal to use his fire during their match at the festival, centered around the point that Shoto deliberately handicapping himself could endanger people who might have been saved if he used all the skills at his disposal. This actually gets Shoto to use his Quirk to its full capacity for the first time in years, which nearly costs Izuku the match he was handily winning before Izuku started working through Shoto's issues.
• With Great Power Comes Great Responsibility: Let's face it, it would hardly be a Spider-Man tale if this didn't pop up somewhere. Surprisingly though, it's Shoto who brings up the phrase while telling off his father in chapter 23.
• Worf Had the Flu: In canon, Stain gave Izuku a very hard, dangerous battle; here, Izuku catches Stain by surprise in his own hideout, with Peter as backup, and Stain is recovering from serious injuries from a previous fight, so the villain is at the wrong end of a Curb-Stomp Battle.
• Worthy Opponent:
  • More like "Worthy Obstacle" – as much as Bakugo despises Peter for being superior to him and his inability to deny the fact, this just fuels his ambitions to surpass his classmate and acknowledges him as a challenge to overcome. The fact that Peter's the first classmate for Bakugo to openly refer to by his actual name signifies that he has greater respect for him than he's willing to admit.
  • Played with regarding All For One. He certainly can respect his opponent, but that all depends on how much of a threat they are to him. If they oppose him but ultimately fail, then he gives them his respect (i.e. Shimura Nana). If they go against him and succeed, then he'll have nothing but scorn for them and dismiss them out of spite (i.e. All Might).
• Wrong Context Magic:
  • Since Peter's powers are derived from the spider bite, he passes his abilities off as a Quirk that gives him the proportional abilities of a spider in order to avoid arousing suspicion. But since it isn't actually a Quirk, abilities that specifically target Quirks don't work on him. Monoma finds himself unable to copy his powers and Word of God also confirms that Eraser Head's Quirk would be completely ineffective on him.
    • Retconned ever-so-slightly later, where Peter's "Quirk" is labelled during the Sports Festival as a Mutation-Type (which Aizawa's Quirk also doesn't work on.)
    • To be fair, that's just what people are assuming his powers are, and it's not like Peter can correct them without getting unwanted attention.
  • In a sense, the MCU's powers compared to the MHA world's powers in general. MHA's powers and technology are all derived from human ingenuity or Quirks, while powers and tech have more diverse, non-Quirk-based origins in the MCU.
• Your Head Asplode: The thermite charge Momo attaches to the back of the USJ Noumu's neck vaporizes the monster's spine and head and a good chunk of its upper body.
